Description

(5) ELECTROMAGNETIC FILTER SEPARATOR

one

The invention relates to the enrichment of minerals and can in particular be used for the purification of liquids from ferromagnetic particles.

A electromagnetic filter is known that includes a housing, an electromagnetic system located on the outside of the housing, and a ferromagnetic attachment located in the housing, supplying and discharging pipes.

Also known electromagnetic filter separator, comprising a housing, a main and additional electromagnetic systems, placed respectively on the outer and inner sides of the housing with the formation of an annular gap in which the ferromagnetic attachment is placed, inlet and outlet nozzles L2.

A disadvantage of the known devices is the low efficiency of the cleaning process, since the magnetic field lines are concentrated

near the surface of each electromagnetic system.

The purpose of the invention is to increase the efficiency of the cleaning process.

The goal is achieved by the fact that the electromagnets of the main electromagnetic system are placed in mutually perpendicular planes displaced relative to the electromagnets of an additional electro magnetic system by half a MeiNT of the electromagnet, and the size of the annular gap is determined from the ratio

where I is the interpolar distance of the electromagnet.

The drawing shows the proposed

20 filter separator, longitudinal section.

The filter separator includes a housing 1, the main electromagnetic system consisting of electromagnets 2, qo33

an electromotive electromotive system consisting of electromagnets 3, a ferromagnetic nozzle 4, a casing 5 of the inlet 6 and an outlet 7 of the sockets.

Shifting the electromagnets of the primary and secondary systems by half the interpolar distance of the electromagnet allows the poles of the electromagnets of both systems to be placed at the same distance from each other, which causes the magnetic flux circuit between the opposite poles of the primary system and the opposite poles of the primary and secondary systems. Such a magnetic flux distribution makes it possible to create a high-gradient electromagnetic field in the entire volume of the ferromagnetic packing;

Filter separator works as follows.

The source material through nozzle 6 is supplied to a volume filled with a ferromagnetic packing. Magnetic particles are attracted to the elements of the nozzle, and non-magnetic particles are discharged through the nozzle 7. When the device operates in filter mode, the purified from ferromagnetic impurities is discharged through the nozzle 7.

The creation of a high-gradient magnetic field throughout the ferromagnetic packing makes it possible to increase the efficiency of the separation process.
